TQ @ZZ o/:zomt may concern Be it known that l, LEON HAIN, a subject of the Czar of Russia, residing at Philadelphia, in the county of Philadelphiaand Sta te of Pennsylvania, have invented certain new and useful improvements in Detachable Heel-Sections, of which the following is a specification. 4

My invention relates to improvements in detachable heel sections, 'the object of the invention being to provide a boot'or shoe with a permanent heel section and a removable heel section comprising the lower portion of the heel, so that when the removable heel section is worn, it may be replaced by a new heel section without the necessity of having the heel repaired by a skilled shoe maker.

A further object is to provide improvements of this character which when in position, will resemble the ordinary heel, and will have a firm locking juncture, so that the section cannot work loose or be released.

A further object is to provide improvements of the characterstated which are of extremely simple construction, neat 'and attractive in appearance, strong and durable. in use.

With these and other objects in view, the invention consists. in certain novel features of construction and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the claims.

In the accompanying drawings: Figure 1 is a fragmentary view in 'longitudinal section illustrating my improvements. Fig. 2 is a view in transverse section on the line 2 2 of Fig. 1. Fig. 3 is a bottom plan view of the permanent heel section. Fig. 4f is a top plan View of the removable heel section. Fig. 5 is a view in transverse section illustrating a modified form of removable heel section.

1 represents a boot or shoe, and 2 a permanent heel section which is formed on the shoe in the ordinary manner and which is provided on its lower face with a metal plate 3. This plate 3 conforms in shape to the shape of the heel. It is appreciably smaller than the heel and extends to the front edge of the heel where it is provided with a recess 4. The outer edge of the plate 3 is conccntric'with the outer edge of the heel, and is beveled as shown at 5. The

able section 7, I secure a thin steel`plate 8 having a U-shaped metal frame 9 secured thereto by rivets 10d. ln other words, the

plate 8 and frame 9 are rigidly secured to* gether by the rivets l0, and screws or other suitable securing devices 11 are projected through openings in the frame 9 and plate 8 and screwed into the removable section 7. In the preferred form ofv my invention, the upper face of the removable section is ref cessed to accommodate the plateand frame 9, so that the leather or other material of the section extends to the upper edge of the removable section, .and entirely hides the metal. l

In the modification .illustrated in Fig. 5, the plate 8 and frame 9 extend entirely to the edge of the removable section in which case l shall preferably so color the metal that it will not attract attention. The plate 8 is formed of thin steel ribbon, and at its forward edge is provided with two recessesA 12 which form between them, a spring tongue lhaving a block 14 xed to the free end of the tongue and constitutinga spring catch, said block engaging in the recess 4 of the plate 3. The inner face of said blocks is undercut orjinclined downwardly and inwa-rdly as at lie, while the adjacent forward face of said permanent heel section is correspondingly inclined as at l5', to receive the beveled face 14 of the said block 14 in locking engagement when the removableA heel section is properly adjusted to the shoe heel proper,and by this arrangement it is obvious that the removable heel section will not only be locked against sliding movement but the forward edge, as well as the other edges thereof, will be held against sagging ordropping downwardly. The removable section 7, at its forward edge, has a recess 15 back of the spring tongue or catch soas to allow the latter a suiiicient movement to release itself from engagement with the recess simply necessary to insert the finger nail or ,I

4 of plate 3. The'inner edge of frame 9is' tudinally. l Fig.'1 shows the parts in normal position. When the removable section is worn, itis some instrument between the-block 14 and the permanent heel section 2, and press the block downwardly out of the recess 4. This engagement of the block is facilitated by reason of thefact that the forward edge of the block is beveled as shown 4at 17, and it theframe 9, are beveled as shown at 18 toY preventcutti-ng the leather-ofl thefvpermanent heel section 4when the removable section is these beveled portions 17 andv 18 facilitate the assemblageof the removable heelA sec-y tion, as they serve to guide the parts toheela will be like new.l It will be. observed.

that when the parts are together, that. the

plate 8 forms la smooth contacting surfacel engaging the plate?, throughout thelentire surface of the latter, and as the plate and frame 9 ,are of the. same thickness, the heel sections will lie smoothly together and there 'will be no yuneven contacting. surfaces to interfere xwith the perfect connection.

It is to `-`be understood that it is my purposel to supply to the trade, removable heel lsections-.of various sizes and shapes, so that any purchaser can obtain the heels and repair his own shoes in -this manner without the necessity of employing skilled labor.-

In other words', every purchaser of a pair of shoes will know .the size of heel section he will want, andwhen the section becomes worn, he can obtain a new one 1and place it I. y on a shoe'.

Various slight changes might be made in the general form andl arrangement of parts' ldescribedvwithout 'departing from my inven tion, 4and hence lf do not .limit myself to the moved. longitudinally. Furthermore,

precise details set forth, but consider'mysel'f c at liberty to make such changes and altera- 'tions as fairly fallwithin the spirit and scope of the appended claims.

Having thus described my invention, what ters 4Patent is:

1. A permanent heel section having a l plate secured to its lower face with its forward edge flush with the .forward edge of `I claim as nwand desire to secure by Letsaid heel, the vsaid forward edge of 'said f Iplate being recessed and the rear edge of' /said recess beingA beveled, in combination 5 with a removable heel section, said remov:A will-also be noted that the forward ends of able heel section being provided with a plate ward edgeof the sectionto which'it is' attached and provided with means to inten. lock with the edges of the plate on said permanent'heel section, said forward edge of said platel being cut away to provide' a spring. tongue, and a block secured to said tongue to extend upwardly therefrom and providedv at its inner edge with a. beveled surfaceA for locking engagement with 'the' beveled edge-of the recessfon said permanent` heel section, substantially as described.

2. The combination with a permanent 'heel section and a removable heel4 section arranged in sliding interlocking :engagement soy with each other,of a spring tongue-formed upon said latter heel section Hush with the A forward edge thereof and provided with an upwardlyl and inwardly' extending block, the said permanent heel section having its forward edge adjacent said block inclined inwardly and upwardly, and the inner face of said block being inclined downwardly and I inwardly for engagement with the said. forward face lof said permanent'heel section, whereby said 'removable section will be held against. slidingv movement and the forward l edge thereof Awill be held against downward .movement, substantially as described..

In testimony whereof lI have signed my name to this specification in the presence of two subscribing witnesses. 4 7 v v LEON HAIN.
